Idle and Horsepower Problem

Idle and Horsepower Problem
I own a 98' Explorer V8. I have had a problem with what I though was "missing". So i changed out all the spark plugs and this worked good for a while. Now however, it seems to have come back with a low idle and also it sometimes dies now. I also seem to have lost some horsepower, visible by the pick up, which I am sure has to do with this problem.
I am not sure what the problem is and rather than replacing parts at random like the fuel pump, Idle Air Control Valve, spark plug cables ect. I would like to know what is causing this. Is there any way to test these to help eliminate possible causes? Any help would be appreciated.
Thanks
